Re: Luasocket + Luasec not retrieving data from https api

["lua.greatwolf" <lua.greatwolf@...>]

After much investigation, I think I made some progress. It looks like I have
to include "Content-Type" and "Content-Length" in the header for the POST
request. So now instead of getting "{"error":"Invalid command."}", I get
"{"error":"Invalid API key/secret pair."}".

The hmac-sha512 digest is computed from the secret and post data request
sent to the server. Since I get the same hash as in python, I'm guessing
somehow the server end isn't getting the post data correctly.

Anyone have any ideas?

Here's the updated script so far:

The main change is in the header table:

  headers =
  {
    Sign = signature,
    Key = key,
    ["Content-Type"] = "application/x-www-form-urlencoded",
    ["Content-Length"] = #post_data
  },

As a sidenote, I've manually constructed the POST request using the chrome
app addon called "POSTMAN" as a test. The query successfully goes through
when using the following 3 header-fields: Key, Sign, Content-Type with
content type being "application/x-www-form-urlencoded". Filling the body of
the request with "nonce=1399116375497&command=returnBalances" in raw form.

So I'm stumped as to why luasocket+luasec doesn't want to work.
